Summary
Miami International Holdings
finance business enterprise
An exchange holding company whose addresses all answer under an IT provider's domain.
What it's used for
- An options exchange holding company's network. A single IPv4
/24announced from the United States, no IPv6, and one observed BGP neighbour.
Notable
- The AS handle is the company's initials, a counter and then the AS number itself, so the identifier contains its own name.
- All three sampled addresses answered, each with the address written out in dashes under a managed IT provider's domain, a company the registry never mentions.
- The netname is the same initials and counter as the handle, without the AS number.
- Three addresses were queried for reverse DNS and three returned a name.
- Two hundred and fifty-six addresses behind a single upstream.
Interesting
- Reverse DNS naming a provider rather than the holder tells you who runs the network. The exchange holds the registration; somebody else operates the addresses and writes the zone.
- An AS handle ending in its own AS number is a small circularity that shows up more than once in this range. It happens when the registry requires a unique handle and the obvious name is taken.
- A financial exchange group announcing one block through one upstream is a modest footprint for the business. Trading systems live on private circuits, not on the public routing table, so what shows here is the corporate edge rather than the market.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-08, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 455 networks and 1,854 prefixes, as published 2026-11-09. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
